In Paper I (Mickaelian et al. 1999), we compared the surface density of QSOs
in the Bright Quasar Survey (BQS) and in the First Byurakan Survey (FBS) and
concluded that the completeness of the BQS is of the order of 70% rather than
30-50% as suggested by several authors. A number of new observations recently
became available, allowing a re-evaluation of this completeness. We now obtain a
surface density of QSOs brighter than B = 16.16 in a subarea of the FBS covering
2250 deg2, equal to 0.012 deg-2 (26 QSOs), implying a
completeness of 5310%.
